Problems solved by technology

[0002] 50% carbendazim wettable powder is more available in the market, but due to its large dust and low content, it is inconvenient to manufacture, transport and use
Dispersible granules overcome the above-mentioned shortcomings. High-content carbendazim water-dispersible granules can not only increase the field efficacy of the product, but also reduce transportation, environmental pollution and other factors. There are also many studies on water-dispersible granules, but the weight content of carbendazim is mostly below 70%, and most of the water-dispersible granules with carbendazim content higher than 70% do not disintegrate or have poor stability. The development and production of mature high-content carbendazim water-dispersible granules has become a technical issue of common concern to all of us

Embodiment Construction

[0015] The present invention is described in detail below in conjunction with embodiment:

[0016] The consumption of each component in each embodiment is as shown in the table: all are weight percentages in the following table

[0017] Example

[0018] 11

[0019] Example

[0020] In the above examples, the dispersants D450 and YUS-WG4 used can be purchased from public sources. The wetting agent Jierun Morwet EFW can be purchased from the market and provided by Nanjing Jierun Technology Co., Ltd. The preparation method is as follows: according to the aforementioned raw material ratio, the raw materials are pulverized and mixed in a jet mill; after the mixed raw materials are bonded, they are granulated with a 1.0mm screen and dried at a temperature of 20°C to 45°C.

Abstract

The invention discloses a carbendazim water dispersing granule which is characterized by comprising the following components in percentage by weight: 85-95 percent of carbendazim raw medicament, 2-5 percent of dispersant, 1-3 percent of surface active agent, 1-3 percent of wetting agent and 1-4 percent of filler. The carbendazim water dispersing granule has low cost, high medicament effect, good stability, good disintegrating performance, no solvent, no dust, safety for operators and environment, good fluidity, no agglomeration, no wall sticking and favorable automatic dispersibility, can be packaged into a paper bag, and save cost, is free from the influence of water temperature and water quality when in use, plays a certain fertilizer role after the product is used, and plays a yield increase role in crops.

Description

technical field [0001] The invention relates to a carbendazim water-dispersible granule and a preparation method thereof. Background technique [0002] 50% carbendazim wettable powder is more available in the market, but due to its relatively large dust and low content, it is inconvenient to manufacture, transport and use. Dispersible granules overcome the above-mentioned shortcomings. High-content carbendazim water-dispersible granules can not only increase the field efficacy of the product, but also reduce transportation, environmental pollution and other factors. There are also many studies on water-dispersible granules, but the weight content of carbendazim is mostly below 70%, and most of the water-dispersible granules with carbendazim content higher than 70% do not disintegrate or have poor stability. The development and production of mature high-content carbendazim water-dispersible granules has become a technical issue of common concern to all of us. Contents of t...
